"He's definitely not out of the woods in any way, shape or form," stated Boca Raton Police Chief Dan Alexander, at a joint news conference with Delray Police Monday. "He's surrounded by family, surrounded by his law enforcement family," said the chief.

Friday night a Boca robbery case led Detective Mammarella and two other officers to the intersection of Linton Boulevard and Old Dixie Highway in Delray Beach. Mammarella was near the road, on foot, looking for clues when he was struck.

The other officers did not see the car hit Mammarella, but they described a car leaving the area as a dark Volkswagen Passat, or CC. Fortunately for the investigation, a convenience store down the street, Rashed's Food Store, had its surveillance cameras rolling.

The security system captured video of what looks like a dark colored Volkswagen Passat passing in the street, just moments before Detective Mammarella was hit.

"It's getting closer, the net's drawn tighter," said Jeff Messer, spokesman for Delray Beach Police. Messer said his agency is using an auto database to try and track down the car involved. But he said Delray Police are also hopeful the driver will come forward, or members of the public volunteer information.

Messer said, "If you know someone has one of these cars, and now the car is in the shop, or under a tarp, or has vanished mysteriously, let us know."

People may call Delray Beach Police or Palm Beach County Crimestoppers at 1-800-458-TIPS.
